I often use Mathematica notebooks as an informal "lab notebook", plotting recent results in various tabs and such. I've noticed that these files can tend to get really large; for example, my Windows file explorer shows one to be 66MB. Additionally, it can often take about 10 seconds to finish saving a file. It also tends to be a little "laggy" when I scroll around the plots or open/close the tabs (the alt+5 titles that you can collapse) that I use to organize my work.
My first question is: What's causing such a delay? I suspect it's either just having many large datasets (~100,000 pairs) in memory, or maybe it is that when I plot them, the data is still "there"; i.e., the plot isn't just a static image or something.
My second question is: Is there a smarter way I should be doing this? My main concern is usually just producing the plots so I can analyze my data quickly. If it would be faster to raster them so they were just a simple image, that wouldn't bother me.
What's the smartest way to do this? Thank you!
